MacBook Pro MagSafe charging issue after macOS updates

Thank you for taking the time to explain your experience. I understand your frustration, particularly as the same MagSafe charging problem has occurred twice, apparently following macOS updates. Having to wait approximately one month for a replacement charger, only to experience the same issue again, is understandably concerning, especially when you depend on your MacBook Pro for work.

Regarding your question, it is possible that other MacBook users have experienced intermittent MagSafe charging problems. However, the timing of the problem following a macOS update does not, by itself, establish that the update caused it. Intermittent charging can have several possible causes, including the MagSafe cable or power adapter, the charging port, power management, firmware, or macOS software. A proper technical investigation would be necessary to determine the underlying cause.

It is also important to clarify that Apple is not participating in this discussion, and Apple will not necessarily see or receive your comments here.

This is not an official Apple Support channel, and posting your experience here does not constitute a formal complaint or technical report to Apple.

If you wish to pursue this matter and bring it to Apple's attention, I strongly recommend contacting Apple Support directly through its official website:

Contact - Official Apple Support

Alternatively, you can arrange an appointment at an Apple Store or contact your Apple-authorized service provider, MobileCare, and request that the recurring issue be documented and escalated to Apple for further investigation.

When contacting Apple, I suggest providing the following information:

• Your MacBook Pro 16-inch (M4), purchased in December 2025.
• The first occurrence in July 2026, shortly after a macOS update.
• The replacement MagSafe charger supplied through MobileCare.
• The recurrence following the macOS 27.2 update.
• The intermittent connection and disconnection, accompanied by the MagSafe indicator light repeatedly switching on and off.
• The approximately one-month delay you experienced while waiting for the replacement charger.

I would also recommend requesting a case number and asking Apple to investigate whether there is a known software, firmware, or hardware-related issue associated with your particular MacBook model and macOS version.

Given that your MacBook is relatively new and the problem has recurred after a previous repair, it is reasonable to ask Apple for a more comprehensive diagnosis rather than simply replacing the charger again.

I hope you are able to get a definitive explanation and a lasting solution. Most importantly, I hope Apple takes your feedback seriously so that you can rely on your MacBook Pro without worrying about unexpected charging interruptions.

My recommendation: Keep the tone factual and constructive, but insist on having the recurrence formally documented by Apple. The fact that the issue temporarily disappeared does not mean the underlying cause has been resolved.

 Contact Apple for support and service

Thank you for the contact support but I cannot open the page. The charging issue has returned just two hours after I reported here in the community a while ago. The MagSafe charger is once again blinking on and off, and I will likely need to visit the authorized service center again ASAP.

I am concerned that I may have to wait another three to four weeks, even though the problem appears to be with the adapter.

This is extremely disruptive because I rely on my MacBook for work.

I hope Apple and its authorized service centers can provide a faster and more convenient solution for customers experiencing recurring charging issues.
